Kesalahan:EXDEV:tautan lintas perangkat tidak diizinkan, ganti nama '/tmp/ di Ubuntu 16.04 LTS

Permasalahan yang sama. Solusi:Baca file temp, tulis file di lokasi baru dan hapus file temp:

        // Read the file
        fs.readFile(oldpath, function (err, data) {
            if (err) throw err;
            console.log('File read!');

            // Write the file
            fs.writeFile(newpath, data, function (err) {
                if (err) throw err;
                res.write('File uploaded and moved!');
                res.end();
                console.log('File written!');
            });

            // Delete the file
            fs.unlink(oldpath, function (err) {
                if (err) throw err;
                console.log('File deleted!');
            });
        });
